He is still a great hero, and I still admire him just as much. Sexism was as rampant as racism in those days. He honestly admitted he was not good at relationships, and that is more than most husbands at the time. Tesla also had issues with women, and his mother, too, was a brilliant scientist.
If living in the 21st century, I believe most brilliant people would enlarge the circle of compassion to include many others, but time does trap us all.
